I have a macbook pro and I want to connect it to a projector. The projector accepts RCA inputs and s-video input. I got an adaptor thats vga on one side and has both RCA and s-video on the other but neither works with the projector. I know the projector works because I can hook up video game consoles using RCA and there is no problem. The RCA and S-video on the adaptor are female and I have a male-male cord to connect that to the projector.
